[Qemu-devel] [PATCH] i386/kvm: Fix build with -m32

[Max Reitz <mreitz@redhat.com>]

find_next_bit() takes a pointer of type "const unsigned long *", but the
first argument passed here is a "uint64_t *".  These types are
incompatible when compiling qemu with -m32.

Just cast it to "const void *", find_next_bit() works fine with any type
on little-endian hosts (which x86 is).

Fixes: c686193072a47032d83cb4e131dc49ae30f9e5d
